Hello,
Oleg, Chung-chieh Shan, and others have done some work close to this
area. On this page, see the "Monads parameterized by time" section:
http://okmij.org/ftp/Haskell/number-parameterized-types.html
Also see this page:
http://okmij.org/ftp/Haskell/types.html#ls-resources
The new type family stuff being introduced in to GHC should hopefully
go a long way towards making this type of code more readable.
Not sure how easy or hard it would be to enforce the particular
properties you mentioned, but the above references might give you some
idea how to proceed.
